Propulsion Systems Engineering

 At Tek-Edge Inc., we deliver advanced propulsion engineering solutions by blending classic gas dynamics, high-energy thermodynamics, and structural-thermal-fluid multi-physics modeling. Utilizing a fully licensed, premier design and analysis suite, we seamlessly integrate into client development workflows. From initial cycle analysis to high-speed nozzle optimization, our propulsion capabilities ensure your launch vehicles, thrusters, and missile systems achieve maximum specific impulse and robust structural margins. 

We design, analyze, and optimize liquid rocket engine cycles, including pressure-fed, expander, gas-generator, and staged-combustion architectures. Our engineers evaluate the high-pressure fluid dynamics of turbopumps, design high-efficiency injector plates, and perform conjugate heat transfer modeling on regeneratively cooled combustion chambers. These comprehensive system models ensure stable combustion, maximize engine thrust-to-weight ratios, and maintain safe operational margins across volatile propellant combinations. 

We simulate the internal ballistics and structural integrity of solid rocket motors from ignition through burnout. Our team models complex propellant grain geometries, regression rates, and core gas dynamics to predict precise thrust-time curves and internal chamber pressure profiles. Additionally, we analyze the thermal protection insulation and structural case margins to prevent structural burn-through, grain cracking, or catastrophic over-pressurization. 

We optimize the aerodynamic expansion and thermal profiles of converging-diverging nozzles, aerospike nozzles, and thrust-vectoring systems. Our solvers accurately simulate insentropic flow fields, flow separation during over-expanded sea-level starts, and plume expansion in deep-space vacuums. This specialized modeling minimizes divergence losses, maximizes thrust coefficient, and ensures the physical nozzle architecture survives intense aerothermal heating. 

We support the seamless mechanical, thermal, and fluid integration of the propulsion module into the larger launch vehicle or missile airframe. Our engineers evaluate plume-induced base heating, structural thrust-structure load paths, and vibrational acoustics transmitted from the engine gimbal. This multi-disciplinary optimization ensures the propulsion system safely drives the vehicle without compromising aerodynamic control or structural stability. 

We serve as an independent verification and validation body to support physical test campaigns and bridge the gap between simulation and fire testing. We anchor our analytical models against hot-fire telemetry, analyzing high-frequency pressure transducer data, heat flux measurements, and thrust stand readouts. This rigorous data loop validates model assumptions, refines predictive accuracy, and ensures legally defensible design verification before flight qualification.
